The driver reliability factor as the element of system "driver-machineroad conditions" in wheeled vehicles stability ensure

Abstract

The approach to ensure the wheeled vehicle position stability with considering of the driver's reliability factor as element of system "driver-vehicle-road conditions," based on the definition of the stability parameter limit and acceptable values is developed. As the stability parameter is suggested to use the coefficient of dynamic stability KДУ . When KДУ < 1 , the position stability is provided. When there is the danger of tipping over, the driver must apply the appropriate measures to prevent it. Evaluation of the parameter is carried out with mobile registration measurement system with the software product DPSAV (Dynamic Position Stability of Articulated Vehicles). When it reaches certain values of stability parameter, the driver is notified of the danger of tipping over using the built-in audible and visual alarm. The main effect for increase the position stability is obtained by improving the information content and ensures corrective action in motion by means of the mobile registration and measuring complex. The basic approach is in evaluation the current stability parameter in real time, and in the analysis of the collected data sets. Statistical analysis of the results can give a complete picture on any interval of operation time on the implementation of safety requirements for the use of articulated vehicles in the individual case, and in the case of fleet utilization. The results can be used in the operation of articulated wheeled vehicles.
